Midday Nowcast: Hazy, Hot, and Humid

THE THREE Hs: Hazy, Hot, and Humid weather this week, and in fact this will be the hottest week of weather so far this year for Alabama and much of the Deep South. Dew points are in the low to upper 70s across Alabama, and a strong upper ridge will push temperatures into the mid 90s each day. The combination of hot temperatures and high humidity will cause heat index values over 100°, and in many places it will exceed 105° which is the Heat Advisory criteria for all of Central Alabama, and is why we are seeing one today. I fully expect additional heat advisories to be issued each day this week.

The days will feature a partly to mostly sunny sky, while nights will be fair and very muggy. While we don’t expect any organized or widespread rain this week due to the subsidence (sinking air) associated with the upper ridge, rain chances are not zero. Each day there will be random showers or storms and some storms will could be strong due to the very high instability in place…Big HEAT means Big STORMS, expect lots of lightning with storms. The chance of any one location seeing rain today and tomorrow is 15-25 percent; odds will be a bit higher Wednesday and Thursday as the air aloft will be a little cooler (20-40 percent).

THE ALABAMA WEEKEND: Temperatures should be a few degrees lower Saturday and Sunday with highs in the 90-93 degree range; the weather looks mainly dry with sunny days and fair nights. Chance of a cooling shower is very, very small both days.

NEXT WEEK: The upper ridge holds; highs again will be in the mid 90s most days with only isolated afternoon storms. Most likely the pattern will hold through the rest of June;

IN THE TROPICS: All is quiet for now, but an area of low pressure is expected to develop by the middle part of this week over the southwestern Caribbean Sea. Some slow development of this system is possible thereafter while it drifts generally northwestward off the coasts of Nicaragua and Honduras. Formation chance through 5 days…low…30 percent.
